        * configure.host: Add microblaze.
        * libc/include/machine/ieeefp.h [MICROBLAZE]: Define __IEEE_BIG_ENDIAN.
        * libc/include/machine/setjmp.h [MICROBLAZE]: Define _JBLEN, _JBTYPE.
        * libc/include/sys/config.h [MICROBLAZE]: Define _REENT_SMALL,
        _UNIX98_THREAD_MUTEX_ATTRIBUTES.
        * libc/include/sys/types.h: Treat XMK like rtems, define
        PTHREAD_MUTEX_NORMAL, PTHREAD_MUTEX_ERRORCHECK, PTHREAD_MUTEX_RECURSIVE,
        PTHREAD_MUTEX_DEFAULT, PTHREAD_STACK_MIN, define stuct pthread_attr_s.
        * libc/machine/configure.in: Add microblaze.
        * libc/machine/configure: Add microblaze (not regenerated).
        * libc/machine/microblaze/configure.in: NEW.
        * libc/machine/microblaze/configure: Generate.
        * libc/machine/microblaze/Makefile.am: NEW.
        * libc/machine/microblaze/Makefile.in: Generate.
        * libc/machine/microblaze/{abort.c, strcmp.c, strcpy.c, strlen.c,
        mallocr.c, longjmp.S, setjmp.S}: NEW.
        * libc/stdlib/mallocr.c [MICROBLAZE]: Don't declare sbrk prototype,
        mALLOc(): return malloc value.
